JOURNAL-FEEDER.

T0 allwkiom it may concern: I

Be it known. that I, PAUL MpKnmioee,

citizen of the United States, residing at Detroit, county of Wayne,State. of Michigan, have invented a certain new and use ful Improvementin Journal-Feelers, and declare the following to be a full, clear, andexact description of the same, such as will enable others skilled inthe-art to which it pertains to make and use the same, reference beinghad to the accompanying drawings, which form a part of this'application. 7

This invention relates to a device, which I have termed a journalfeeler, designed to indicate whether or not a journal--par-, ticularly acar axle journal-has been scored through the entry of grit or otherforeign matter between the journal and its brasses.

It is customary at present when examining the condition of an axlejournal for the inspector to pass his hand over the surface of thejournal to determine whether it has been scored or not, but the journalis frequently so hot that an examination of this character cannot bemade without danger of injury to the hands of the inspector.

It is therefore one of the objects of the present invention to providemeans whereby the journal may be quickly and easily felt and if scoredthe depth and extent of same may be determined without danger to thehands of the inspector.

In the accompanying drawings Figure 1 is a longitudinal vertical sectional view through a car axle bearing, showing the journal feeler indotted lines as when testing a journal.

Fig. 2 is a side elevation of the device with parts broken away and insection to more clearly show its construction, and'indicating in dottedlines the handle folded back against the body of the device that it maybe more readily carried in the pocket.

Fig. 3 is an enlarged cross-sectional view on or about line 3-3 of Fig.2.

Fig. 4 is an enlarged cross-sectional view on orabout the line 4-4 ofFig. 2.

Fig. 5 is an enlarged longitudinal sectional view through the handleshowing the battery, and lamp connections.

Fig. 6 is a cross-sectional view through i Specification o'f LettersPatent. Patented F91 1921.

the handle and lamp socket on or about line -66 of Fig. 5.

Referring now to the letters of reference placed upon the drawings A, isa slightly tapering tubular arm comprising two opposing portions A Asecured together by boltsB. The forward end of the tapering arm has aright angle portion A bored for the passage of astyle or stylus C, whichprojects through the beveled end A of the right-angle portion.

D, indicates a swingingrod 'ournaled'in a suitable jeweled bearingsecured to the inner wall of the tapering arm. The rod D, is'provided atits free end with a pointer D adapted to traverse a graduated dial E,projecting beyond the opposite end of the tube and integral therewith.

F, is a spring secured at one end in the wall of the tube, its oppositeend bein formed with a hook toenga e the rod to normally urge the style(5 on the end of the rod to project through the inclined or beveled endA of the tubular arm as shown in Fig. 2.

G, is a tubular handle, serrated on its outer face to provide a bettergripping surface, and rovided with a removable closure cap G at itsouter end to admit an electric battery H, urged forward by the action ofthe spring H. The handle G is provided with a rojecting arm G pivoted atI to a lug J integral with the graduated end of the tubular arm.

Adjacent to the graduated dial on the end of the tubular arm is anelectric bulb K, supported in a suitable lamp socket K secured to theend of the tapering arm A.

L, denotes a spring latch carried by and is opened upon swinging thehandle G to the position shown in dotted lines in Fig. 2.

Having now indicated the several parts by reference letters theconstruction and operation of the device will be readily understood;

The cover P of the journal box P hav 7 ing been raised, as indicated indotted lines in Fig. 1, and the cotton waste removed 100 tween thebattery and the lamp K, which I therefrom; the operator thrusts thedevice into the journal box that the stylus C may travel over thesurface of the bearing, which if grooved or cut will force the stylus tomove up and down due to the action of the spring F thereby causing therod D to swing its pointer D over the graduated dial E that the depthand extent of the grooves in the journal may be determined. The lightbulb being located adjacent to the dial the device may be used toadvantage in the dark as well as in the light.

When the handle is swung backto the position shown in dotted lines thelight is.

thereby turned off, while the device is more readily adapted for thepocket.

Having thus described my invention what I claim is a In a device of thecharacter described, a

tubular member having a transverse extension at one end adapted totraverse a journal bearing and an extension provided with a graduateddial at the opposite end, a handle attached to the tubular member, aswinging rod journaled in said tubular member and adapted to traversesaid graduated dial, a spring adapted to act upon said rod, and a stylusconnected with the swinging rod extending through the transverseextension of the tubular member, whereby it may be brought intoimpinging relation with an axle journal.

In testimony whereof, I sign this specification in the presence of twowitnesses.
